epe tets iit b ed sea -VFIEJI'IL t r eshes? e -"added e M dj c nt f" flange 13 projecting laterally in the same direction to overlap the flange 12. The flange 12 is wider than the flange 13 and is bent back upwardly to extend around the edge of the flange 13 and overlap and bear on said flange 13. In this manner, the edge portion 1 1 of the flange 12 is clamped around the ed e portion of the flange 13, and the flanges are soldered together, as at 15. A broad up: wardly facing surface is thus provided to receive the solder, in order that the seam can be sealed to good advantage. The solder is also located as far as possible from the base of the seam where the greatest strain or separation occurs, in order that the solder will not be broken by any slight separation of the edges of the sheets.

In order to drag the sheets back into place during the contraction thereof transversely, expansion and contraction strips 17 are laid on the sheathing 13 o-f'the roof under the sheets 7 and extend transversely of said sheets. Wherever each strip passes under one of the standing or longitudinal seams, an upstanding anchor piece or cleat 19 is secured on the strip, such anchor or cleat having a foot or base flange 20 riveted or otherwise secured on the strip transversely across the strip, and said anchor or cleat having an angularly extending flange 21 at its upper end. These anchors or cleats are disposed between the portions 10 and 11 of the standing means, and each of said cleats 19 is engaged by at least one of the rivets 16, thereby clamping the cleats in thestanding seams, with the flanges 21 located between the flanges 12 and 13. In this'manner, the cleats or pieces 19 are securely embedded. within the standing seams and being secured on the strips 17 will anchor the seams 9 to the strips 17, whereby, when the sheets 7 expand and contract transversely, the strips 17 expand and contract longitudinally of themselves,

and the roof will expand and contract with said strips. Furthermorawhen the sheets 7 contract transversely, the strips 17 contract longitudinally, and the anchors or cleats 19 being secured in the standing seams, will result in the sheets being dragged back into place with the strips 17.

Each strip 17 in contracting will carry the cleats 19 with it, and such cleats will move the standing seams with them, so that the sheets 7 are dragged transversely of themselves without imposing any appreciably strain on the seams 9. There is therefore a minimum possibility of the seams 9 being injured or torn open. When the strips 17 are in inclined positions, the feet 20 of ,the cleats 19 project toward the upper ends of the strips 17, whereby, during the contraction of the strips 17 a pull is exertedon the feet 20 instead of a compressionforce which would be the case if the feet pro standing cleats secured to the edges jecte d toward the lower ends ofthe strips.

Thus, although the sheets 7 are pushed transversely down the grade or slope of the roof during the expansion thereof, such sheets are dragged back up the incline by the strips 17, without throwing the entire strain on'the standing seams as frequently, with the ordinary standing seams, results in the rivets pulling out or the solder breaking. With the present arrangement, there is but a minimum strain applied to the standthe seams, the sheets being anchored to said strips.
